Rose plant Korflapei

ABSTRACT

A rose variety of the floribunda class is provided having an extremely long vase life for the buds and bright yellow flowers, with the flowers being produced in large quantities and having thick flower petals.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the floribunda class, which was originated by me by crossing anunnamed seedling with the variety Champagne, U.S. Plant Pat. No. 5,411.

The primary objective of this breeding was to produce a new rose varietyof the floribunda class bearing flowers with an extremely long vaselife, exhibiting a high production of flowers for cutting with a brightyellow color. This objective was substantially achieved, along withother desirable improvements, as evidenced by the following uniquecombination of characteristics which are outstanding in the new varietyand which distinguish it from its parents as well as from all othervarieties of which I am aware. For example, this new rose variety has:

1. Extremely long flower vase life;

2. High flower production;

3. Bright yellow flower color;

4. Extremely small receptacle;

5. Thick petals;

6. Few prickles.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagation.

DESCRIPTION OF THE DRAWING

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed description of my new rose cultivar, whichhas been denominated "Korflapei". Color terminology is in accordancewith The Royal Horticultural Society Colour Chart except where anordinary dictionary significance for the color is apparent.

Observations of the buds and flowers were made from specimens grown in agarden at Irvine, Calif. in July.

Flower

This rose plant produces flowers with an extremely long vase life. Cutflowers will last ten to fourteen days under normal vase conditions.

The blooming habit is continuous. The bud size is one to one andone-quarter inches when the petals start to unfurl. The bud form ispointed ovoid. The bud color when sepals first divide is near YellowGroup 12B; when half blown, the upper side of petals is near YellowGroup 12B to 12C fading on the outer petals to White Group 155D, and thelower side of petals is near Yellow Group 12B. The sepals have a colornear Green Group 138B. The surface texture is covered with fine hairs.There are three appendaged sepals normally appendaged, and twounappendaged sepals with hairy edge. The receptacle color is near GreenGroup 138B of a small size, smooth surface and funnel shape. Thereceptacle is of small size with only a slight funnel shape. Thepeduncle is of medium length, smooth surface with an occasional gland.Peduncle color is medium green, and the peduncle is stiff, heavy anderect.

Bloom

Bloom size is small to medium, with an average open size of three tothree and one-half inches, borne singly or occasionally severaltogether. The stems are strong, and medium to short. The form when firstopen is high center. This form is retained to the end. All petals curlback quill fashion. Under normal conditions there are thirty-fivepetals. The upper side of petal is near Yellow Group 12B, as is thereverse side of the petals. The base of petals darkens to Yellow Group12A with the major color being near Yellow Group 12B. There are novariegations. The general tonality at the end of the first day shows nochange in color. At the end of the third day, the outer petals will fadeon the plant, but as a cut flower there is little or no fading.

The fragrance is slight. The petal texture is thick, of a round shapeand the tips are moderately quilled.

The arrangement is imbricated with no petaloids in the center. Theblooms drop off cleanly, and last both on the plant and as a cut flowerfor a very long time.

Reproductive Parts

There are many anthers of medium size, of yellow color and arrangedregularly around the styles. The filaments are yellow, the pollen isgold yellow, the styles are reddish and stigmas are greenish white.

Plant

A very vigorous growth of upright bush form.

Foliage

Medium size, normal in quantity. The new foliage has a slight reddishcast on newest foliage but rapidly becomes green, and the old foliage isdark green. Normal mid-stem leaves have five leaflets.

The leaflets are of an oval pointed shape, are smooth, and have aserrated edge. The serration is single and small in size. Petiole rachisis green and petiole underside is smooth with occasional prickles.Stipules are medium and edged with glands. The foliage is susceptible tomildew under normal growing conditions at Irvine, Calif.

Wood

New wood is green, with a smooth bark. Old wood is green with a smoothbark.

Prickles

There are few prickles on main canes from the base and few on lateralsfrom the main canes. The form is short and straight. Color when young isred.

Parentage

The seed parent was an unnamed seedling; the pollen parent was thevariety Champagne, U.S. Plant Pat. No. 5,411.

Classification

Botanical is rosa hybrid. Commercial is floribunda.

I claim:
 1. A new and distinct variety of rose plant and parts thereofof the floribunda class substantially as herein shown and described,characterized particularly as to novelty by bright yellow flowersproduced substantially continuously in high quantities, cut flowers witha vase life of about ten to fourteen days under normal vase conditions,thick flower petals, few prickles and an extremely small receptacle.
